Baltic Amber Insect Inclusions
Indeterminate insect inclusions cf. Diptera / Hymenoptera • Body fossil (amber inclusion) representing terrestrial arthropods
Geological Period
Paleogene (Eocene epoch)
Estimated Age
33 to 48 million years old
Preservation Type
Fossilization via entrapment and preservation in fossilized tree resin (amber), resulting in exquisite three-dimensional soft-tissue and chitinous preservation.
Condition Assessment
Very Good. The amber pieces are polished and transparent enough to view internal inclusions, with minor surface crazing typical of aged amber.
Taxonomic Classification
Phylum Arthropoda, Subphylum Hexapoda, Class Insecta
Morphological Description
Polished amber cabochons revealing suspended arthropod specimens, showing clear appendages, segmented bodies, and fine cuticular structures preserved in three dimensions.
Rock Matrix
Fossilized tree resin (amber) rather than a traditional sedimentary rock matrix, exhibiting characteristic golden-brown to dark orange translucent properties.
Formation & Location
Baltic amber region, primarily associated with the Eocene amber-bearing strata of the Samland Peninsula in the Kaliningrad Oblast, Russia, and surrounding Baltic Sea coasts.
Size & Dimensions
The amber pieces range from approximately 1 cm to 5 cm in maximum length, typical for polished cabochons containing small insect inclusions.
Value & Rarity
Estimated Market Value
$50 - $200 USD
Auction Estimate
$40 - $150 USD
Rarity Assessment
Common to Uncommon, as Baltic amber with small insect inclusions is widely available on the market.
Scientific Significance
Provides exceptional insights into Eocene forest ecosystems, paleoclimate, insect evolution, and ancient ecological interactions through pristine morphological preservation.
Preparation Recommendations
Store in stable temperature and humidity conditions away from direct sunlight and UV radiation to prevent oxidation, crazing, and degradation of the amber.
Notable Features
Clear visibility of trapped inclusions within polished amber fragments, displaying natural flow lines and warm golden-brown coloration.
